SPECIFICATION forming part of Letters Patent No. 745,044, dated November 24, 1903. 7

Application filed May 15,1903. Serial No. 15 7,212. (No modelffi To all whom, it may concern.-

Be it known that I, \(VILLIAM DUNN, a subject of the King of Great Britain and Ireland, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Golf-Clubs; and Ido hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is designed to provide a golfclub with a head of such a characteras to materiallyincrease the driving power of the club and which while possessing this and other characteristics which particularly adapt it for efficient service may be formed or molded in a single unitaryintegral structure requiring no supplemental leading.

In the accompanying drawings, Figure 1 represents a top plan view of agolf-club head, illustrating one of the forms in which my invention may be applied in practice, said figure also illustrating a portion ofthe drivingshaft to which the head is attached. Fig. 2 represents a longitudinal section of the head and an elevation of the end of the shaft,taken on a plane through the securing-aperture.

The characteristic feature of my invention consists in constructing the golf-club head of pyralin or xylonite (which I find best adapted for the purpose) or some similar or analogous pyroxylin composition. The form or configuration of the head preferred by me is that shown in the drawings, wherein the driving-surface a is shown as almost fiat, the rear surface I) as irregularly rounded, and the main bulk of the material being carried by the forward portion 0 of the head. The sides are parallel and substantially at right angles to the face for a short distance, so as to aid in fixing the direction of the shot. The head is provided with a taperingaperture,as shown, for the reception of the correspondingly-tapered end of the shaft (1, the bottom of the aperture being substantially in the center of the head. I regard this construction as of particular value,for the reason that'when formed or molded of the material specified a structure is presented which entirely dispenses with the necessity of leading the head and reduces the leverage around the shaft toa minimum, thus lessening slicing and pulling and greatlyimproving direction. This is due not only to the configuration and distribution of the material in the head, but also to the high specific gravity of the material beyond that of wood 'or the like. Furthermore, these desirable attributes are present in combination with others, which are of remarkable service for this particular use. For instance, the elasticity of the head is greatly augmented in spite of the increased specific gravity, and this elasticity is uniformly distributed in view of the unitary character of the structure. Furthermore, the head, though resilient, because of its elasticity, thereby yielding upon impact against the golf-ball and correspondingly lessening the jar upon the shaft, nevertheless resumes its normal shape with such extraordinary prompt-ness that the energy momentarily stored up by the blow within the head is almost instantly imparted to the ball, so that the latter receives the full benefit of the momentum of the head.

I wish it to be understood that I do not confine myself wholly to the particular configuration of golf-club head illustrated in the drawings, although, as I have said, I regard that form as of particular service and as probably the best adapted for the purpose. In this connection the manner ofjointing the end of the shaft to the pyralin head seems to be of particular importance, inasmuch as the distribution of the strains due to the impact blow from the head to the shaft is realized in away which minimizes the liability of fracture either of the head itself or of the shaft at the point of juncture. It will also be noted from the conventional illustration in Fig. 2 that what may be called the grain of the pyralin is located longitudinally of the striking-face,which arrangement not onlystren gthens the head to resist breaking strains, but enables it to exert to its fullest degree the elasticity and resilience, which are such important factors in its action.

Having thus described my invention, what I claim is 1. A golf-club head formed of pyralitn or other pyroxylin compound, the grain of the right angles to the striking-surface; substan- IO compound being longitudinally disposed in tially as described.
